Expedited liver transplantation as first-line therapy for severe alcohol hepatitis: ELFSAH; deferring corticosteroids in the sickest subset of patients.

BACKGROUND & AIMS: Severe alcohol-associated hepatitis (SAH) represents a lethal subset of alcohol-associated liver disease. Although corticosteroids are recommended by guidelines, their efficacy and safety remain questionable and so liver transplantation (LT) has been increasingly utilized. The timing and indication of corticosteroid use, specifically in patients being considered for LT requires further clarification. METHODS: A retrospective analysis was conducted on 256 patients with SAH between 2018 and 2022 at a single US center. RESULTS: Twenty of these patients underwent LT. Of the 256 patients, 38% had what we termed "catastrophic" SAH, defined as a MELD-Na ≥35 and/or discriminant function (DF) ≥100, which carried a mortality of 90% without LT. Compared with 100 matched controls, patients undergoing LT exhibited a one-year survival rate of 100% versus 35% (p < .0005). LT provided an absolute risk reduction of 65%, with a number needed to treat of 1.5. Steroid utilization in the entire cohort was 19% with 60% developing severe complications. Patients administered steroids were younger with lower MELD and DF scores. Only 10% of those prescribed steroids derived a favorable response. Sustained alcohol use post-LT was 20%. CONCLUSIONS: We propose ELFSAH: Expedited LT as First Line Therapy for SAH; challenging the current paradigm with recommendations to defer steroids in patients with "catastrophic" SAH (defined as: MELD-Na ≥35 and/or DF ≥100). Patients should be seen urgently by hepatology, transplant surgery, psychiatry and social work. Patients without an absolute contraindication should be referred for LT as first-line therapy during their index admission.

A novel scoring system to predict survival in cirrhotic patients undergoing isolated lung transplantation: The PENS-CEPT score.

Cirrhosis is usually regarded as a contraindication to isolated lung transplantation (ILT). We sought to determine which patients with cirrhosis could safely undergo ILT. Based on a retrospective analysis of patients with cirrhosis who underwent ILT at our center between 2007 and 2020, we developed an exclusionary algorithm (PENS-CEPT: Pittsburgh ExclusioN Score in Cirrhotics Evaluated for Pulmonary Transplant) to help determine which patients can undergo ILT with minimal incurred risk from their underlying liver disease. The score utilizes a combination of readily available clinical data and the presence (or absence) of spontaneous portosystemic shunts on preoperative cross-sectional imaging. Sixteen patients underwent ILT with a diagnosis of cirrhosis: nine with cystic fibrosis. On univariate analysis, only our model was able to predict 1 year survival. Of the nine patients that would have been approved using our model, there was only one short term death. Of the seven patients that would have been rejected by the model, all but one died within the first year with six dying of complications from liver failure. We are proposing a simple score utilizing routine clinical parameters and pre-operative imaging to determine the safety of ILT in cirrhotic patients. Further studies are required to validate this scoring system with the goal of safely increasing the opportunity for cirrhotic patients who would otherwise be rejected for ILT.

Characterization of hepatic steatosis using controlled attenuation parameter and MRI-derived proton density fat fraction in living donor liver transplantation.

BACKGROUND: The increasingly favorable outcomes of live donor liver transplant warrant development of screening techniques to expand current donor pool. Transient elastography (TE) with controlled attenuation parameter (CAP) is accessible and has promising diagnostic performance in non-obese individuals. Here, we demonstrate its utility in grading donor steatosis for risk assessment in living liver donors (LLD). STUDY DESIGN: In a prospective study of LLD and recipients, accuracy was determined using MRI-derived proton density fat fraction (PDFF) as reference. RESULTS: One hundred and one LLD underwent TE, 95 of whom had available PDFF. Median CAP and MRI-PDFF were 233 dB/m (206-270) and 2.9% (2.3-4.0), respectively. A CAP threshold of 270 dB/m captured all steatosis which was present in 13 (13%) LLD (AUROC .942, 100% sensitivity and 83% specificity). Performance further improved when excluding obese LLD and limiting analysis to M-probe (AUROC .971 and .974, respectively, with 87% specificity). There was no difference in CAP and MRI-PDFF between LLD and nondonors (P = .26 and .21, respectively). Early allograft dysfunction was observed in one recipient (CAP 316, PDFF 9.5%), zero underwent retransplant, and one died from sepsis. CONCLUSION: The specific role of CAP in living liver donation warrants further study, beginning with its use as screening tool across peripheral clinics.

Idiopathic pneumatosis intestinalis secondary to lactulose use in patients with cirrhosis.

BACKGROUND AND AIM: Few case reports exist that link lactulose use with pneumatosis intestinalis in cirrhotics. This study investigates the relationship between lactulose use and idiopathic pneumatosis intestinalis in a cohort of cirrhotic patients. METHODS: This case series considers several notable cases of patients with idiopathic pneumatosis intestinalis and concurrent lactulose use. Idiopathic pneumatosis intestinalis was defined as pneumatosis intestinalis with no identifiable etiology. A cohort of 119 patients with cirrhosis and pneumatosis intestinalis were identified in a tertiary care setting, via chart review by a multidisciplinary team. Eleven of these patients were found to have idiopathic pneumatosis intestinalis. Nine of these patients were being treated with lactulose. RESULTS: Six out of 9 patients with idiopathic pneumatosis intestinalis that were being treated with lactulose saw resolution of pneumatosis intestinalis following discontinuation of treatment. CONCLUSIONS: The etiology of idiopathic pneumatosis intestinalis is likely multifactorial, but lactulose might play a preventable role in its formation.

Hernia Management in Cirrhosis: Risk Assessment, Operative Approach, and Perioperative Care.

BACKGROUND: The rising incidence of liver disease has complicated the management of common surgical pathologies. Hernias, in particular, are problematic given the shortage of high-quality data and differing expert opinions. We aim to provide a narrative review of hernia management in cirrhosis as a first step toward developing evidence-based recommendations for the care of these patients. MATERIALS AND METHODS: A literature review using separate search strings was conducted for PubMed and Cochrane Central Register of Controlled Trials databases. Review articles, conference abstracts, randomized clinical trials, and observational studies were included. Articles without a focus on patients with end-stage liver disease were excluded. Manuscripts were selected based on relevance to perioperative risk assessment, medical optimization, surgical decision-making, and considerations of hernia repair in patients with cirrhosis. RESULTS: The existing literature is varied with regard to focus and quality of data. Of the 4516 articles identified, 51 full-text articles were selected for review. In general, there is evidence to suggest that individuals with compensated cirrhosis may successfully undergo and benefit from hernia repair. Patients at high risk for decompensated cirrhosis may be best served by nonoperative management. CONCLUSIONS: Carefully selected patients with cirrhosis may proceed with herniorrhaphy. A multidisciplinary approach is essential to provide high-quality care and improve outcomes.

Incidence of Recurrent NASH-Related Allograft Cirrhosis.

BACKGROUND: Cirrhosis secondary to nonalcoholic steatohepatitis (NASH) is projected to become the leading indication for liver transplantation (LT) in the USA in the next decade. The long-term implications of post-LT NASH, specifically on the development of allograft cirrhosis, are not well known. METHODS: A retrospective cohort of patients at a single large center undergoing LT for NASH from 2000 to 2015 was identified using a prospectively collected database. A total of 226 patients undergoing LT for NASH were identified. Mean follow-up for the cohort was 7 years. Seventy-five percent of patients underwent at least one liver biopsy post-LT. RESULTS: Eighty-one patients (36%) developed recurrence of biopsy-proven NASH. Fifteen patients developed bridging fibrosis but only four patients (1.8%) progressed to recurrent NASH cirrhosis at a mean of 9 years post-LT. Body mass index at the time of LT was statistically higher in the NASH allograft cirrhosis group. Recurrent disease was less common and less severe in those transplanted with black donors. All four patients with recurrent NASH cirrhosis developed evidence of portal hypertension, but all remained alive at follow-up. CONCLUSION: Although recurrent NASH following LT is common, the development of allograft cirrhosis is rare. These findings are useful when counseling patients and important to consider during their post-LT care.

Linear IgA Bullous Dermatosis Preceding the Diagnosis of Primary Sclerosing Cholangitis and Ulcerative Colitis: A Case Report.

Linear IgA bullous dermatosis (LABD) is a rare autoimmune blistering disorder seen in the pediatric and adult populations that is often linked to a medication, infection, or underlying gastrointestinal, hepatobiliary, or autoimmune disease. In this study, we describe the case of a 23-year-old white man whose presentation and diagnosis of LABD ultimately led to the discovery of underlying primary sclerosing cholangitis (PSC) and ulcerative colitis (UC). His dermatitis resolved with topical steroids and dapsone, and he is undergoing systemic treatment for his UC and PSC. This exceptional case further validates the association between LABD with UC, strengthens that with PSC, and underscores the importance of alerting clinicians to consider conducting a systemic workup in addition to thorough medication history on making the diagnosis of LABD.

Cemiplimab-Associated Sinusoidal Obstruction Syndrome.

A 58-year-old woman developed new-onset recurrent ascites after the recent initiation of cemiplimab for the treatment of advanced basal cell carcinoma. A comprehensive serological workup for viral, metabolic, and autoimmune causes was unrevealing. Transjugular liver biopsy demonstrated parenchymal changes consistent with a diagnosis of sinusoidal obstruction syndrome. While this is a condition commonly observed in patients after hematopoietic stem cell transplantation or use of chemotherapeutic agents, it should also be considered in patients who develop new-onset liver dysfunction after the initiation of checkpoint inhibitors.

Risk Factors and Outcomes of Postoperative Hepatic Dysfunction After Lung Transplantation.

BACKGROUND: Hepatic dysfunction is a morbid complication of lung transplantation. Little is known about risk factors for postoperative hepatic dysfunction or its impact on survival after lung transplantation. METHODS: This retrospective analysis of 1406 adult lung transplant recipients was performed at the University of Pittsburgh Medical Center in Pittsburgh, Pennsylvania between January 1, 2007 and December 1, 2019. Patients were excluded for redo lung transplantation, concomitant cardiac surgery, or concurrent solid organ transplantation. Postoperative liver dysfunction was classified as either ischemic liver injury or nonischemic dysfunction (transaminitis, hyperbilirubinemia). RESULTS: Among the 1155 primary lung transplant recipients included, postoperative hepatic dysfunction developed in 96 (8.3%) after lung transplantation. A history of liver disease was the greatest predictor of postoperative hepatic dysfunction (odds ratio, 6.19; CI, 2.13-17.4; P < .001). Patients with postoperative hepatic dysfunction had a greater need for intraoperative blood products (ischemic, 12 U [range, 6-21 U]; nonischemic, 10 U [range, 4-28 U]; vs none, 4 U [range, 1-12 U]; P < .001) and an increased need for postoperative circulatory support (ischemic, 16 [76%]; nonischemic, 25 [33%]; none, 117 [11%]; P < .001). Both ischemic liver injury and nonischemic dysfunction were associated with diminished 1-, 3-, and 5-year term survival (ischemic, 27.5%, 16.5%, and 0%, respectively; nonischemic, 60%, 49.6%, and 46.9%, respectively; none, 87.3%, 72.3%, and 59.5%, respectively; P < .001). CONCLUSIONS: Hepatic dysfunction after lung transplantation is associated with significant morbidity and mortality. A history of liver disease was the best positive predictor for postoperative dysfunction. Additional studies are necessary to identify the best treatment algorithm to avoid hepatic dysfunction more effectively in the postoperative setting after lung transplantation.

Incidence of hepatocellular carcinoma in nonalcoholic fatty liver disease without cirrhosis or advanced liver fibrosis.

BACKGROUND: HCC can develop in the absence of cirrhosis in patients with NAFLD. We aimed to estimate the incidence of HCC in patients with NAFLD with and without cirrhosis or advanced liver fibrosis. METHODS: We performed a cohort study to determine the incidence of HCC in patients with NAFLD identified by the International Classification of Diseases 9/10 codes in the electronic health records of a US health care system between 2004 and 2018. The incidence of HCC was stratified by the presence or absence of cirrhosis and by the Fibrosis-4 index (FIB-4) at the time of HCC diagnosis. RESULTS: Of 47,165 patients with NAFLD aged 40-89 years, 981 (2.1%) developed HCC (mean follow-up 3.4 y). Among patients with HCC, 842 (85.8%) had cirrhosis, while 139 (14.2%) did not. Of the 139 patients with HCC without cirrhosis-related diagnostic codes, 26 (2.7%) had FIB-4 >2.67 (advanced fibrosis likely), whereas 43 (4.4%) had FIB-4 < 1.30 (excluding advanced fibrosis). The annual incidence of HCC in patients with NAFLD with and without cirrhosis was 23.6 and 1.1 per 1000 person-years, respectively. Among patients without cirrhosis, the annual incidence of HCC was 2.8 per 1000 person-years with FIB-4 >2.67 and 0.7 per 1000 person-years with FIB-4 <1.30. Patients with NAFLD and cirrhosis were 31.8 times (95% CI, 23.3-43.4) more likely to develop HCC than those without cirrhosis and FIB-4 <1.30, after adjustment for age and sex. CONCLUSIONS: Patients with NAFLD without cirrhosis nor advanced fibrosis have a low incidence of HCC.

Spontaneous bacterial peritonitis before liver transplantation does not affect patient survival.

BACKGROUND & AIMS: Spontaneous bacterial peritonitis (SBP) is a devastating complication of cirrhosis with high mortality. The impact of a prior episode of SBP on the outcome of liver transplantation (LT) is not well known. We aimed to determine the short- and long-term morbidity and mortality of patients who received LT, with and without a history of SBP. METHODS: We reviewed the records of all adult patients who underwent LT at a single center between June 1999 and June 2009. Patients with SBP were compared with all other patients who underwent LT during the same time period, without prior episodes of SBP. RESULTS: A total of 1491 adult patients underwent LT in the study period; 80 (5.4%) had at least 1 episode of SBP before LT. The mean follow-up time for all patients in the study was just over 4 years. Patients in the SBP cohort were more likely to be male (74%) and to have alcoholic liver disease. Patients with SBP had higher Child-Pugh and model for end-stage liver disease scores at the time of transplantation compared with controls, but there was no difference in long-term mortality between the 2 groups. Patients with SBP, however, were more likely to require surgery for complications related to LT within 1 year and were more likely to die of sepsis. CONCLUSIONS: Despite higher Child-Pugh and model for end-stage liver disease score at the time of LT, survival times of patients with SBP before LT are similar to those patients without SBP.

Hepatitis C recurrence is not adversely affected by the use of donation after cardiac death liver allografts.

Many factors can worsen a recurrent hepatitis C virus (HCV) infection after liver transplantation (LT). We sought to determine whether the use of donation after cardiac death (DCD) livers affects HCV recurrence. From January 2000 to June 2008, 37 HCV patients underwent LT with DCD allografts. The outcomes and severity of HCV recurrence were analyzed along with those for 74 matched control patients with HCV who received donation after brain death (DBD) livers. The 2 groups had similar donor and recipient characteristics, immunosuppression regimens, rates of acute cellular rejection (ACR), and HCV profiles. DCD patients had a higher incidence of primary nonfunction (19% versus 3%, P = 0.006) and significantly higher peak aspartate aminotransferase levels in comparison with DBD subjects, suggesting a greater degree of ischemia/reperfusion injury. Although the survival rates were not significantly different, DCD recipients had lower 1- and 5-year patient survival rates (83% and 69% versus 84% and 78%, respectively, P = 0.75) and graft survival rates (70% and 61% versus 82% and 74%, respectively, P = 0.24). Three hundred fourteen protocol and clinically indicated liver biopsy procedures were performed within 6 years after transplantation, and mixed modeling analysis showed that fibrosis progression rates were similar for the 2 groups (0.6 fibrosis units/year according to the Ishak modified staging system). The rates of severe HCV recurrence (retransplantation or death due to recurrent hepatitis C and/or the development of stage 4/6 fibrosis or worse within 2 years) were similar [3 DCD patients (8%) versus 11 DBD patients (15%), P = 0.38], and cytomegalovirus infection (hazard ratio = 7.9, P = 0.002, 95% confidence interval = 2.1-28.9) and ACR (hazard ratio = 6.2, P = 0.002, 95% confidence interval = 2.0-19.7) were the only independent risk factors for severe recurrence. In summary, although there was a trend of poorer overall outcomes in DCD patients, the use of DCD livers did not appear to adversely affect HCV recurrence after LT.

Liver transplantation in patients with nonalcoholic steatohepatitis-related hepatocellular carcinoma.

BACKGROUND & AIMS: The increasing incidence of hepatocellular carcinoma in the United States is only partially accounted for by hepatitis C virus (HCV) infections. The prevalence of hepatocellular carcinoma in patients with nonalcoholic steatohepatitis (NASH) is not known; guidelines from the American Association for the Study of Liver Diseases do not recommend surveillance imaging. We sought to determine the prevalence of hepatocellular carcinoma among patients undergoing liver transplantation for NASH-related cirrhosis and their outcome after surgery, compared with controls. METHODS: We reviewed the records of adult patients with NASH cirrhosis who underwent liver transplantation by using a prospectively collected database from a single center. Data from patients with NASH cirrhosis were compared with matched controls who received transplantation for primary biliary cirrhosis/primary sclerosing cholangitis, alcoholic liver disease, or HCV. RESULTS: Seventeen of 98 patients (17%) with NASH cirrhosis were diagnosed with hepatocellular carcinoma. The mean age was 63 years, and 70% were male. Six patients were diagnosed with hepatocellular carcinoma incidentally on explant. Survival after liver transplantation was 88% after mean follow-up of 2.5 years. The number of NASH patients known to have hepatocellular carcinoma before liver transplantation was greater than the number of patients with primary biliary cirrhosis/primary sclerosing cholangitis and comparable to the number of patients with alcoholic liver disease and HCV. CONCLUSIONS: Patients with NASH cirrhosis are at risk for developing hepatocellular carcinoma; patients with NASH cirrhosis, especially men older than 50 years, should undergo surveillance imaging. Patients with NASH and hepatocellular carcinoma have good outcomes after liver transplantation.

Recurrent disease following liver transplantation for nonalcoholic steatohepatitis cirrhosis.

Recurrence of the original disease following liver transplantation is not uncommon and can lead to graft failure. There are limited data on recurrent fatty liver disease following liver transplantation. The aim of this study was to determine the incidence of recurrent fatty liver disease in patients with biopsy-proven nonalcoholic steatohepatitis, its effect on survival, and whether there are any predictive factors for recurrence. We analyzed patients undergoing liver transplantation for nonalcoholic steatohepatitis cirrhosis from 1997 to 2008 at a single center. Patients undergoing transplantation for cholestatic disease, alcohol, hepatitis C, or cryptogenic cirrhosis were controls. Ninety-eight patients underwent transplantation for nonalcoholic steatohepatitis cirrhosis. Recurrent fatty liver disease was seen in 70%, 25% had recurrent nonalcoholic steatohepatitis, and 18% had stage II/IV or greater fibrosis at a mean of 18 months. No patients with recurrent nonalcoholic steatohepatitis developed graft failure or required retransplantation at a follow-up of 3 years. No recipient or donor factors were associated with disease recurrence, although patients with recurrent nonalcoholic steatohepatitis had a higher incidence of diabetes, weight gain, and dyslipidemia at the time of diagnosis of recurrence. One-third of patients with recurrent nonalcoholic steatohepatitis had normal liver enzymes at the time of diagnosis post-transplantation. In conclusion, recurrent fatty liver disease is common following liver transplantation for nonalcoholic steatohepatitis cirrhosis but does not lead to early allograft failure. Recurrent nonalcoholic steatohepatitis can occur despite normal liver enzymes, and features of metabolic syndrome are associated with disease recurrence.
